Spaceborne unified data & information network

This paper gives an application of SpaceWire Network on transferring spaceborne data & information. The on-board data is classified as payload data and platform management data. Accordingly, the on-board network is divided into payload data subnet and platform data subnet that are used to deliver payload data and platform management data respectively. Two different high-level protocol stacks are selected for the two subnets to satisfy the different transmission demands of payload data and platform management data.
